Benefits of technology

[0025]As shown in the preceding technical solution, before switching the VOD server, the global load balancer provided in embodiments of the present invention makes a judgment according to the current running status of each VOD server and a polic

Problems solved by technology

Due to instable network transmission, however, when VOD server 1 provides video streaming services for the user terminal, the link between VOD server 1 and the user terminal may be broken due to the jitter or congestion of the transmission link.
Thus, VOD server 1 cannot continue to serve the user terminal.
In this case,

Embodiment Construction

[0030]The present invention is hereinafter described in detail with reference to preferred embodiments and accompanying drawings.

[0031]As shown in FIG. 3 and FIG. 4, a system provided in an embodiment of the present invention includes a user terminal such as a set top box (STB) or a personal computer (PC), at least two VOD servers that are adapted to provide VOD services for user terminals, and a global load balancer. The process of implementing VOD services is as follows:

[0032]Step 1: A user terminal sends a VOD request to the global load balancer.

[0033]Step 2: The global load balancer selects an optimal VOD server according to the running status of each VOD server and a policy, such as the first VOD server.

[0034]Step 3: The global load balancer forwards the VOD request sent from the user terminal to the first VOD server.

[0035]Step 4: After detecting that the first VOD server providing VOD services is down because the first VOD server is really down or the user terminal is disconne...

Abstract

A method for improving video on demand (VOD) service reliability includes: selecting a first VOD server to provide VOD services for a user terminal; and reselecting a second VOD server according to the current running status of each VOD server and a policy to continue providing VOD services for the user terminal after receiving a VOD request re-initiated by the user terminal. The present invention avoids blind switchover of VOD services, greatly improves the switchover success ratio, and ensures the quality of the VOD services provided for users.
